Brian Brown, the president of the National Organization for Marriage (NOM), on Monday touted West Virginia Rep. Nick Rahall's endorsement of a proposed federal gay marriage ban.

Rahall is the first Democrat to sign on as a co-sponsor to the proposed legislation, which was introduced by Kansas Rep. Tim Huelskamp, a Republican, within days following the Supreme Court knocking down the Defense of Marriage Act (DOMA) and clearing the way for same-sex marriages to resume in California.

Brown held up the addition of 12 co-sponsors since the bill's introduction as proof that his side is winning.

“The proposed amendment now has over 40 cosponsors signed on!” Brown wrote in a blog post. “Most significantly, it has been announced that the first Democrat (hopefully of many!) has joined as a cosponsor: Rep. Nick Rahall of West Virginia's 3rd District!”

“Rep. Rahall's support proves once again that marriage is an issue that cuts past partisan politics and special interests, speaking universally to our shared common sense principles, such as every child's right to have both a mom and a dad.”

“The progress already made on getting this amendment to a vote on the floor of the House is only possible because NOM supporters like you band together and take the time to tell your elected leaders that you, and the majority of Americans, stand for marriage – and that those who represent us in Washington need to do the same,” he added before asking for a donation.

However, a 2004 attempt to approve a similar amendment at a time when public opposition was at its peak (60%) and only 1 state had legalized marriage equality failed to clear Congress. Nearly a decade later, with support hovering above 50 percent and 13 states plus the District of Columbia having approved such unions, passage seems far less likely.
